Southover (Lewes) have won the Sussex Primary Schools' Championships.
The team included brothers Alex and Tom Harris, plus Joe and Robbie Eyles, who are all Sussex players.
Southover crushed Herne (Crowborough) 3-0 in the final at Eastbourne to win the Millennium Cup.
They also had whitewash wins against West St Leonards, Ocklynge, Parkside, Silverdale and St Peter St Paul.
Also in the team were Daniel Marshall, Freddie Possegger, Josh Fawsett and Adam Stapleton.
Herne were also unbeaten on their way to the final after victories against Guestling Bradshaw, Willingdon, Cross In Hand, St Leonards and High Hurstwood.
Southover coach Kevin Marquess said: "It was a doubles competition but we kept the brothers apart because they don't play as well together."
The Harris brothers are the sons of Colin, a former county squash champion.
It is the second time in three years Marquess has coached Southover to glory and he was also in charge when Plumpton won in 2000 and 2001.
Ocklynge (Eastbourne) won the Challenge Shield with an 2-1 win against Willingdon in the final.
Mark Trott, the Ocklynge head, said: "We're big on sport and this shows how well our after-school badminton club has developed."
Ocklynge: Richard Hamblyn, Chris Johnstone, Grace Gausden, Tara McCarthy, Marilyn Messenger, Michael Bracuti.
England junior internationals Heather Olver, Bronwyn Powell and Kirsten Read have all played at the championships.
HEATHER Olver, who celebrated her 18th birthday this week, hopes to clinch two titles this weekend.
The England junior international, from Heathfield, competes in the England Under-19s Doubles Masters finals at Milton Keynes.
It is a competition for the top four age group pairs in the country. Olver, a student at Heathfield Community College, competes with Jenny Wallwork (Yorkshire) in the girls' doubles and Harry Wright (Lancashire) in the mixed event.
LUKE Thomson, 14, from Chiddingly, has been selected to represent England in the Home Countries Under-15s International in Glasgow next month. It will be his fourth cap.
